In the Khartoum Resolution of 1967 the members of the Arab League declared what became known as the "Three Nos": "no peace with Israel, no recognition of Israel, no negotiations with it..."
Since then, two members, Egypt 1979 and Jordan 1987 have made peace with Israel. In August and September UAE and Bahrain have declared intent to normalize relations with Israel.
This brings the total of Arab League members with normalized relations with Israel in 2020 to four.
How many Arab League member states will have normalized relations with Israel in 2027?
This question will resolve as the number of states in the Arab League (according to Wikipedia) which maintain diplomatic relations with Israel and have not suspended relations according to Wikipedia, as of October 9, 2027.
In order for the State of Palestine to count towards the resolution, Israel must recognize Palestine as a sovereign state, the recognition of Israel by Palestine as part of the Oslo accords is not enough.
If the Arab League is dissolved before the resolution, the question resolves ambiguously, unless there is an official successor organization.
The Arab League has 22 members as of 2020. if the membership expands, the theoretical number resolution of this question can exceed 22, making >22 a valid option.
If Israel becomes a member of the Arab League, it will be excluded from the resolution count.
